SS flexible pipe DN16, double, insulated

The insulated stainless steel tube represents the perfect solution for a professional connection of the components of a solar system or for applications that require extreme temperature intervals.

The ease of installation, low heat losses and low cost position the flexible stainless steel pipe the optimal solution for installing solar panels with vacuum tubes.

The product consists of two stainless steel tubes AISI 316L (round-trip) wrapped in insulation from expanded elastomer with closed cells, which guarantees perfect insulation up to 175°C. The tube is supplied with an electric cable with two wires integrated inside, to connect the probe to the solar controller that manages the installation.

Mounting specifications:

The tube is cut in such a way that the cut remains clean, without any visible bumps or edges. You can install sockets through swing operation or quick seals sealed with silicone gaskets.
